Which Ohio city is cheapest for home addition?
4 of the 8 metros sit above the statewide midpoint of $56,600, and the top-to-bottom gap is 8%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.

|---|---|---|---|
| Columbus, OH | $38,900 – $78,700 | $58,800 | +4% |

What carpenters and the other trades earn in Ohio
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 6 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.01 for Ohio.
For carpenters (47-2031, weighted 50%) the local median is $29.24 an hour, which is in line with the national $29.12. The middle half of them earn between $23.42 and $36.47 an hour. BLS counts 18,450 of them working in the state, 33.2 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $30.28 an hour, which is 10% above the national $27.41. The middle half of them earn between $23.64 and $36.86 an hour. BLS counts 6,060 of them working in the state, 10.9 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Electricians (47-2111), 10% of the weighting: a median of $31.11 an hour, in line with the US median of $30.38. The middle half of them earn between $24.10 and $38.70 an hour. About 28,950 work in the state. That is 52.2 per 10,000 jobs, compared with 48.7 nationally, so the supply of crews looks typical.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $30.45 an hour, which is in line with the national $30.67. The middle half of them earn between $24.06 and $40.51 an hour. BLS counts 16,390 of them working in the state, 29.5 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Drywall and ceiling tile installers (47-2081), 10% of the weighting: a median of $29.53 an hour, 4% above the US median of $28.33. The middle half of them earn between $23.65 and $34.11 an hour. About 1,680 work in the state. That is 3.0 per 10,000 jobs, compared with 5.3 nationally, so expect fewer local crews to bid.
For roofers (47-2181, weighted 10%) the local median is $23.74 an hour, which is 11% below the national $26.65. The middle half of them earn between $22.14 and $30.40 an hour. BLS counts 4,610 of them working in the state, 8.3 for every 10,000 jobs (US: 8.7), so the local bench is about average.
A crew paid at the 75th percentile for carpenters ($36.47 an hour) would add about $4,750 to the statewide midpoint; one at the 25th percentile ($23.42) would take off about $3,800. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 5,550,180 jobs across Ohio (May 2025), which is 3.6% of US employment.

Weather windows across Ohio
Season matters for home addition. For each Ohio metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for digging and ground work.
Cincinnati has the longest comfortable season of the metros we cover in Ohio at 9 months (March through November); Youngstown has the shortest at 8 (April through November). Rainfall runs from 32 inches a year in Toledo to 43 inches in Cincinnati.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
